Lightswitch error: Load operation failed for query 'GetAuthenticationInfo'

Hi,

I'm getting the dreaded
'Load operation failed for query 'GetAuthenticationInfo'. The remote server returned an error: NotFound' when I try to launch a just published lightswitch app.

Has anyone on this site dealed with it, and succesfully make it work?
I've been trying all the different publishing options from Lightswitch regarding authentication (windows, forms, not enabled) and none works.

I'm hosting it here since today (June 30th) on a Win 2008, ASP.NET 4 Integrted App pool, IIS 7 with manager access to slected user, SQL2008.

Any ideas?

 

Never mind. Found it on Knowledge Base

I found it here, on Knowledge Base.
Used Fiddler2 to find out the detail of the problem, and then it was just a matter of adding the following lines to web.config:

<system.webServer>
<security>
<authentication>
<basicAuthentication enabled="false" />
</authentication>
</security>
</system.webServer>
